(Cl. 53-53) The machines for wrapping bare or packed objects with a cellophane sheet i.e. the so-called cellophane-wrapping machines, are of great importance in the field of wrapping machines.

The cellophane material used for the wrapping is introduced in these machines in the form of bands which are wound up to form rolls. The length of the bands varies according to the diameter of the rolls and the thickness of the cellophane.

Since the cellophane rolls used up to some time ago had a relatively small diameter the length of the band which was wound thereon was small and the wrapping ma chines had to be stopped quite often in order to replace the rolls.

Said rolls were made in general of a continuous seamless band and therefore leaving out the above mentioned halts, which were required for replacing the rolls, they did not cause any other disadvantages nor require any further stopping of the machine as a consequence of de fects of the band.

To reduce the inconveniences originating from the frequent halts of the machine it has been recent practice to use rolls of much larger diameter than ever before. Said large rolls present however several other disadvantages. First of all, they cannot consist of a single continuous band but, on the contrary, they comprise several bands which are jointed together.

Every time a band section comprising a junction or a seam reaches the members of the cellophane-wrapping machine it brings about a wrapped object which is to be discarded. Furthermore it also very often causes mechanical and operational inconveniences as a consequence of jams and the like.

The discarding of the objects which are defective because they are wrapped up with a cellophane sheet comprising a seam must be effected manually and, since this is not always possible, said defective objects often pass to successive working phases.

Another disadvantage inherent in the rolls with large dimensions lies in the fact of their great inertia, their considerable weight and the consequent handling difiiculty but, primarily, in the fact that, due to difficulty in winding, the outermost turns of the band may not be tight and the roll, being quite flabby, is subject to deformations and other inconveniences.

The present invention relates to a device for the practical and very rapid replacement of the rolls as well as for the jointing of the new band at the free end of the exhausted one, said device of the invention allowing the use of seamless cellophane rolls with an average diameter which are well wound and tight, the time required for the replacement of the rolls as well as the maintenance expenses being considerably reduced while, at the same time, the output is more regular and constant and the discarding of the object which is wrapped with a defective sheet is effected automatically.

The novel invention is hereafter described by way of example only and in no limitative sense by referring to the accompanying drawings in which:

FIG. 6 is a plan view of a detail of the novel device;

FIG. 7 is a view taken along the line 14-14 of FIG. 6; and

FIG. 8 is a partial electro-mechanical diagram of the device of the invention.

In all the figures and sections the same reference numerals are used to indicate the same parts of the device.

The stationary and the movable parts of the device are fixed to, and respectively guided in a stationary base support of the machine which is not represented.

In accordance with the present invention the feeding mechanism comprises two roll supports 21, 22 which are adapted to function alternatively and to support the respective cellophane rolls 28 and 29, and the respective cellophane bands 39 and 31 which unwind from rolls 28 and 29.

In the device shown in FIG. 1 the device is represented while the cellophane band unwinds from the roll 28.

The device also comprises a roller 23 mounted on the oscillating feel arm 24 which is pivoted to the stationary base support, said roller 23 being adapted to come into contact with the cellophane roll 28 (as shown in FIG. 1 with a continuous line) or with the cellophane roll 29 (as indicated in the same figure with a dotted line), a tension spring 25 being provided for holding the roller 23 pressed against the cellophane roll, it comes in contact with.

The oscillating arm 24 is provided with projections 26, 26'. When the cellophane roll while the roller 23 leans against is about to be exhausted, said projections come into contact with corresponding electrical push buttons 27-27 that close an electrical circuit and actuate a ringer or some other signal means (not represented) calling the attention of the service personnel.

Hence the forewarning that the cellophane roll is about to be exhausted is given 'by a contact which is determined by the lowered position of the oscillating arm 24 by means of the contact 26 and 27.

The cellophane band 30 turns around a guiding roller 32, passes on another guiding roller 43 and beneath a manually controllable stop pawl 44 and, sliding in the direction of the arrow, it arrives over a further guiding roller 33 and the unwinding and feeding roller 34 to the not represented cellophane wrapping machine.

The band 31 passes on to a roller 43 and beneath a manually controllable stop pawl 44'.

In the section comprised between the roller 43 and the roller 33 the band 30 passes between a fixed anvil body 35 and a welding head 36 which is provided with a heated electric element and a thermostat 37, said head being continuously maintained at the right temperature and ready to effect the welding of the cellophane which, as is usual, is thermoadhesive (thermogluing). Said elements constitute a welding device.

The stop pawl 44 having the unwinding band 30 passing beneath it is lifted, as illustrated in FIG. 1, and is no obstacle to the passing band. The pawl 44 beneath which the stationary band 31 is disposed, is lowered by pressing (by the action of a not represented spring or weight) the band 31 against the roller 43' so as to prevent said band from moving away.

Thus the end 40 of the band 31 which is placed by hand on the anvil body 35 is maintained fixed in position on said anvil body (FIG. 1).

The welding head 36 is pivoted in 38 on the base support of the machine and may occupy two different positions, namely the one which is shown with a continuous line in FIG. 2 (which leaves completely free to the movement of the band 30) and the other one which is shown with dotted line in FIG. 2, at which said welding head presses the cellophane band against the anvil body 35.

The welding head 3-6 is provided with a handle 39 for the manual control and with a projecting part 41. When the welding head 36 presses against the surface 35, said projecting portion 41 pushes the press button 42 to close an electric circuit which will be described later on.

The operation of this portion of the device is the following:

FIG. 1 shows the mechanism as operating in a general functional phase. The cellophane band 3% is unwinding from the roll 28 and is fed over the unwinding rollers 34 to the cellophane-wrapping machine.

The roll support 22 carries a roll 29. The band 31 of the roll 29 is unwound manually and its end portion 40 is brought over and beyond the anvil body 35 and beneath the unwinding cellophane band 30. This operation may be easily carried out manually while the roll 28 is unwinding, since the band 3t) and the anvil body 35 have a free space defined therebetween which is easily accessible from the outside (FIGS. 1 and 2).

When the roll 28 is about to be exhausted the projection 26 of the feel arm 24 presses on the push button and closes the contact 27 which actuates the alarm signal calling the attention of the operator. While holding the exhausting roll 28 under control the operator displaces the oscillating arm 24 to bring it into contact with the roll 29 where, during the whole successive cycle, it remains ready for giving the alarm signal when said roll 29 is about to be exhausted. Said signal is transmitted by having the contact of the projection 26' contact the corresponding push button 27 which closes a contact that is connected in parallel with the contact closed by the push button 27.

When the roll 28 is exhausted the operator opens the switch of the cellophane-wrapping machine (not shown in the drawing) and thus brings it to a halt. Immediately afterwards he lowers by means the handle 39 the welding head 36 against the anvil body 35. The resistance 37, which is already at the right temperature, operates the thermowelding of the trailing end portion of the band 36 with the leading end of the band 31. The operator cuts with scissors the band 30 just before the anvil body, lifts the welding head in the position indicated with a continuous line in FIG. 2, releases the band 31 by lifting the pawl 44 and resets the cellophane-wrapping machine into motion by closing the switch.

The above mentioned operation is quite simple and very rapid.

The operator removes the exhausted bobbin 28 from the bobbin support 21 and sets on said support a new roll which stays there ready to replace the roll 29 once the latter is exhausted.

For this purpose the operator unwinds from the new roll a band section 30 the length of which is just sufficient to have the end of said band 30 reach a position on the anvil body 35, which is above the band 31 and under the action zone of the welding head 36. Hereafter it fixes the band 30 in the correct position by having the pawl 44 press on it. In this way the device is ready for effecting the successive jointing of the band from the new roll 2% with the end of the band from the bobbin 29 and so on and on.

These operations may be carried out without hurrying while the cellophane-Wrapping machine goes on with its wrapping.

By lowering the welding head the operator ha not only welded the band but also closed, by means of the push button 41-42, the electric circuit which operates a memory system and a lag discarding mechanism which brings about the discarding, from the production line, of the object which, has been wrapped with a sheet comprising a seam between the two bands.

This may be effected in many different ways. To render the specification of the invention more complete there will be described hereinafter a preferred but not limitative embodiment of the memory and lag discarding system.

According to the device illustrated in FIGURES 35, the objects are wrapped with cellophane, which is unwound from the rolls in the described manner, by means of a conventional (not represented) cellophane wrapping machine. Hence, said objects are combined into groups (of for instance: five objects for each group) and are brought to a transfer disc 46 which is provided with cavities 47, each of which is adapted to receive the groups of objects 45 which are introduced therein at the station A by means of conventional devices. The disc 46 intermittently rotates in the direction of the arrow 48 whereby each cavity 47 is made to successively stop at said supply station A, at the discarding station E, at an auxiliary supply station C and at successive stations until it reaches the outlet station D.

The intermittent rotation of the disc 46 is controlled by the cellophane wrapping machine through a conventional (not represented) kinematic chain in such a manner that the disc 46 moves the distance comprised between two cavities 47 each time that, at the station A, the corresponding cavity has received a group of objects 45. In the given example the groups comprise five objects and the rotation takes place every five wrapping cycles of the cellophane-wrapping machine.

At the periphery of the disc 46 which goes from the station A to the station D there is provided a side wall portion 50 which is suited to prevent the objects from falling out from the cavities 47.

The disc 46 has stationary supports 49, 49 disposed therebeneath to support the objects 45 in the cavities 47 during the movement of the disc. In the station B said supports are omitted and replaced by tongue portions 51-51 which may be displaced outwards in the direction of the arrows 52, 52 by the action of the electromagnets 53, 53, when the electromagnets are excited, said tongue portions 51, 51' being biased to in the position shown in FIG. 5 by the tension spring 54.

At the station C above the disc 46 there is an auxiliary storage place 55 which may be supplied manually with objects 45 that are already wrapped in cellophane. Said storing place is made of vertical guide portions and is open at the lower side so that at each stop of the disc 46 its lower outlet opening comes in register with a cavity 47.

The station D has conventional means (not represented) disposed therein for removing the objects 45 from the cavity 47 and bring them to further working stations (e.g. to station for wrapping packages of objects).

The discarding of the defectively wrapped object from the disc 46 is controlled by an electromechanical memory and lag device which is represented in FIG. 6 and FIG. 8.

Said memory lag device comprises a wheel 56 which is adapted to turn in the direction of the arrow 58 about a stationary axis 57. The wheel 56 has a series of equidistant axial openings disposed on a circle having the same axis 57 Said holes have pins 59 freely sliding there with a rubber ring 60 encircling and transversely pressing on said pins thereby causing a limited friction.

In said holes said pins may occupy a rest position (shown with a continuous line in FIG. 6) or an operative position wherein they protrude outward as shown with dotted line in FIG. 6.

The rotation of the wheel 56 is controlled by the cellophane wrapping machine over a conventional and not represented kinematic transmission chain in such a way that, for every operative cycle of the machine corre sponding to the output of a wrapped object from the cellophane-wrapping machine, the wheel 56 rotates in the direction of the arrow 59 through an angle which corresponds to the distance between two successive pins 59. An electromagnet 61 has an armature 62 moving parallelly with respect to the pins in opposition to a tension spring 63 and carrying a head 64 which moves in line with the circle of pins 59 and which, when the electromagnet 61 is excited, strikes against the pins 59 which are disposed opposite thereto, thereby pushing them from the rest position into their operative position. The head 64 covers a periphery section which corresponds to the distance comprising two pins 59 so that, by lowering said head, at least one and at most two of said pins are pushed into operative position.

In another position of the periphery around the wheel 56 there is a right angle lever 65 which is pivoted at 66 on the base support and is acted upon by a tension spring to lean against a stationary stop 68, said lever having a projecting part 69 extending into a region opposite to the circle of the pins 59 so as to interfere with the movement of the pins into operative position.

An electric push button 70 is placed at the side of the lever 65 and is adapted to close a circuit every time the projecting portion 69 is struck by a pin 59.

The keyingon phase of the wheel 56 is such as to have every pin 59, which is displaced outwards into operative position, strike against the lever 65 thereby pushing it to close the contact of the push button 70 only during the halts of the transfer disc 46.

In a position of the disc which comes after the position in which the lever 65 enters into function and before the one in which the head 64 starts acting there is a stationary cam 71, with an inclined profile which brings the pins 59 back into their rest position after they have acted upon the lever 65.

The electric circuit with the above mentioned push buttons and the electromagnets is diagrammatically represented in FIG. 8.

The transformer 72 feeds a first circuit including the push button 42, the electromagnet 61 and ground 77.

The same transformer also feeds a second circuit including the electromagnet 74 of the relay 73, the push button 70 and ground 77. When the relay 73 is closed the circuit of the electromagnet 74 is closed from ground 77 through the switch 75 which is as acted upon by the cam 76 so that the relay stays closed even when the contact 70 is opened again.

The relay also closes a circuit extending from transformer 72 through electromagnets 53 and 53' to ground 77.

The cam 76 is actuated by the cellophane-wrapping machine or by the transfer disc by means of a kinematic transmission chain in such a manner that, when the disc 46 is about to move, the cam 76 opens the circuit.

The operation takes place as follows: each time the operator eifects a welding the push button 42 closes the circuit of the electromagnet 61 which attracts the armature 62 the head of which displaces into an active position one or at most two pins 59.

The number of the pins which are present between the operative position of the head 64 on the pins 59 and the one of the pins 59 on the lever 65 is so chosen that the pin, which is displaced into operative position, requires for reaching and acting upon the lever 65 the same time which is required by the sheet comprising the seam to reach the discarding station B. In this way, when the object wrapped up with the defective sheet has come to the discarding station the pins 59, which are in an operative position, close the switch 70 thereby exciting the electromagnet 74 and, through the contacts of the relay the excitation of the discharge electromagnets 53-53. These last overcome the force of the tension spring 54 and the friction of the objects which are placed above the support tongue portions 51, 51' and are remove-d from the lower side of the cavity 47 so that the group of objects comprising the one which is defectively wrapped up, falls into a (not represented) collection container disposed therebeneath and may afterwards be discarded at ease.

When the disc 46 starts moving the cam 76 opens the circuit of the electromagnet 74 which is deenergized and opens the contacts of the relay thereby deenergizing the electromagnets 53, 53 so that the tongue portions 51, 51' by virtue of the action of the spring 54, return underneath the space the cavities 47 pass through, thereby providing for the continuity of support for the groups of objects which must be fed towards the discharge station D.

When a cavity 47 has been emptied in the discard station B it arrives in its empty state at the auxiliary supply station C which is fed by the storage place 55 dropping therein a certain number of objects 45 in accordance with the height of the cavity 47. In spite of the discarding of the defectively wrapped up object, which is effected at the station B, is therefore possible to always have the cavities 47 arrive at the discharge station D .in their completely filled state.

The supply of objects into the storage place 55 is usually carried out manually by utilizing that portion of the object discarded at the station B which are regularly wrapped up in cellophane and by replacing the defectively wrapped objects with new ones.

In this way it is possible to realize:

(a) The possibility of utilizing bands which are wound on rolls with an average diameter, said rolls being easily handled, well wound up and without any defects;

(b) A very rapid and practical replacement of the rolls;

(c) The automatic discarding from the production line of the objects which are wrapped in a cellophane band section comprising a welding seam.

While there has been shown and described what is considered to be a desirable and novel embodiment of the invention it is obvious that changes in form could be made without departing from the spirit of the invention and it is not wished to be limited to the precise form herein shown and described, nor to anything less than the whole of the invention as hereinbefore set forth and hereinafter claimed.

In particular:

Instead of a single commutatable feel arm there may be provided one feel arm 24 for each roll;

The roll supports may be more than two;

The movements of the feel arms, of the pawls and of the welding head may be all or in part connected to each other and possibly also with shears provided for cutting the cellophane;

The discarding position for the defectively wrapped objects, may be chosen at will on the production line of the objects coming out from the cellophane-wrapping machine and may be adapted to discharge and discard a single object only or a group of objects;

The discard device may be operated by a single magnet with two pins or only one pin, with transmission means and the like etc.;

The said discard device may be opened also during the movement of the disc 46;

The system for operating the lagged discarding may be of any other convenient type different from the described one;
